This repository demonstrates how to interface a 7-segment display with the STM32F446RET6 microcontroller using pure register-level programming. There is no additional software framework like HAL or CubeMX involved. This method offers a clear understanding of microcontroller operation.
Follow the simple steps below to set up and run the software on your device.
- Operating System: Windows, MacOS, or Linux
- Microcontroller: STM32F446RET6
- IDE: STM32CubeIDE
- Basic Knowledge: Familiarity with connecting hardware is helpful but not essential.
- 7-Segment Display: For displaying digits.
- STM32F446RET6 Development Board: Where the code will run.
- Wires: For connecting the display.
- Power Source: Connection for powering the board.
